The Stenlille Large-Scale CO2-Storage Demonstration Project

Seismic surveys were conducted in February 2022 (for further information - in Danish - please visit at our Stenlille site to investigate the potential for storage of CO2 in the underground adjacent to our existing methane storage operation. Results from the seismic look promising. The reservoir at Stenlille does not have a capacity that in itself makes for a long-term and large-scale solution for CO2-storage. Though, a CO2-storage project at Stenlille could bring acceleration, speed and valuable knowledge to the deployment of the Carbon Capture and Storage (CCS) technology in Denmark already from 2025, thereby buying Denmark time to develop the larger storage projects in the North Sea and elsewhere towards 2030 and beyond.

Therefore, in June 2022 we have decided to initiate the next stage of the project, the front end engineering and design (FEED) process. This stage is expected to run until end 2022. After this a final “go” or “no-go” decision for the construction of a CO2-storage in Stenlille can be made. It is the ultimate owner of Gas Storage Denmark, the minister for climate, energy and utilities, that eventually will take this decision.

The purpose of the Stenlille CO2-storage project is two-fold:

  • It can enable Denmark reach the politically agreed target of capturing and storing up to ½ mio. tons of CO2 by 2025 at the latest. Specifically by making ourselves available as a low-risk and easily accessible CO2-storage option for the industrial CO2 emitters that will be contesting in the first tender of the CCUS Fund (KEI20). The tender runs over the course of the second half of 2022.
  • To create a platform for innovation and acceleration of the CCS-technology in Denmark. The platform will be used to disseminate and share technical reservoir knowledge as well as experience with early industry standards in the integrated value chain “from chimney to underground” to promote accelerated development of the industry. Specifically for this purpose Gas Storage Denmark is hosting and contributing actively to a number of research projects under the Innomission framework in collaboration with universities and others.
